“…It indicated the role of non-additive gene action for the expression of this trait. This result is similar to the result reported by [24]. The mean square values of GCA were highly significant for all the studied traits, indicating the ample amount of genetic variability present among the studied parental materials.…”

Eleven morphologically diverse cultivated eggplant accessions were used for hybridization following half diallel mating design to obtain 55 hybrids. Evaluation of hybrids along with the parents was conducted over two locations followed by randomised complete block design with three replications to study gene action and combining ability of 15 morphological and biochemical traits. The analysis of variance indicated highly significant differences among the environments and interaction of genotype and environment, except for fruit length to width ratio. Additive gene effects were significant for the inheritance of these traits and expression of these additive genes were greatly affected by environments. The general combining ability (GCA) was greater than their respective specific combining ability (SCA) for all traits except for fruit yield per plant. High values of GCA and SCA effects for characters of interest were dispersed among different genotypes. From this study it was observed that the best parental line was BT15 based on days to first flowering, total number of fruits per plant, total soluble solids and total phenol content. Besides, the parent BM5 showed good general combining ability effects for fruit yield per plant, fruit length and fruit length to width ratio and the parent BB1 performed good general combining ability for fruit diameter, fruit girth and fruit weight. Besides, other parents showed the best performance for only one trait. On the other hand, the hybrid BT6 × BT15 was reported bearing early flowering with high total phenol content and the hybrid BM9 × BB26 has high fruit yield with high soluble solids. Besides, the hybrid BM9 × BB1 has a high fruit diameter and fruit weight. All other hybrids except for these three (BT6 × BT15, BM9 × BB26 and BM9 × BB1) were shown the best performance for only one trait. Hence, based on the desired trait, the hybrid can be selected for future use after large scale evaluation.

The results of ANOVA for combining ability revealed that the mean sum of squares for both GCA and SCA were highly significant for all the traits under investigation (excluding days to 50% flowering). This indicates the involvement of both additive and non-additive gene actions in the inheritance of all analyzed traits while, for days to 50% flowering only the GCA mean sum of squares was highly significant which indicates that additive gene action was involved in the inheritance of this trait. The σ 2 SCA was higher than σ 2 GCA for all traits which earlier recorded for both types of significant gene action denoting the prevalence of non-additive gene action for these traits except days to 50% flowering. The highest GCA effect was observed in AB-08-14 for fruit yield plant -1 , fruit diameter and number of marketable fruit plant -1 . AB-08-14 × GBL-3, AB-08-14 × Pusa Kranti and JDNB-110 × NBL-15 were the top 3 best specific combiners for fruit yield plant -1 . Furthermore, the parents with the best per se performance were also observed as the best general combiners indicating a positive coalition between per se performance and GCA and the hybrids with high SCA effects do not necessarily involve the parents exhibiting high GCA effects. Which showed the importance of inter-allelic interactions for the inheritance of such traits. SCA which have non-fixable genetic materials were potential parameters for heterosis breeding for brinjal where, commercial exploitation of heterosis is feasible and choice of best hybrid combination based on GCA and SCA effects supplemented with per se performance could be more realistic and useful.

“…Eggplant contains a higher content of free reducing sugars, anthocyanin, phenols, glycoalkaloids (solasodine) and amide proteins. Eggplant is well known for its medicinal properties (Pramila et al, 2020). Combining ability is prerequisite in any plant breeding programme either for varietal improvement or for evolving a hybrid.…”

Present investigation was carried out during two summer seasons of 2018 and 2019 on a private farm in Gharbia Governoratethe with 15 genotypes including 5 lines and 10 F1's of eggplant. The experiment was laid out in Randomized Block Design with four replications. The observations were recorded for 10 characters. The obtained results cleared that both GCA and SCA were highly significant in vegetative traits, earliness and fruit characteristics. The ratio between GCA / SCA were more than one in all studied traits under study. The estimates of General combining Ability effects (gca) indicated that parent 1 was best general combiner for fruit yield as number and weight of fruits, whereas the best specific crosses were cross 3 ×4 for number of fruits per plant and crosses 1 × 4 and 3 × 5 were best specific combiners for total fruit weight. Heritability estimates in broad sense were high for all studied traits, while heritability estimates in narrow sense were low for all studied traits except for chlorophyll content it was moderately high.
